Supermodel Heidi Klum has broken her silence on her split from Seal in her first interview since the couple's marriage broke down, insisting she never cheated on the British singer. The German beauty separated from the "Kiss From A Rose" singer in January after almost seven years of marriage, and she filed for divorce in April.

However, the split recently turned nasty when Seal accused his former partner of embarking on a romance with the former couple's bodyguard, telling TMZ.com, "I certainly don't expect Heidi to all of a sudden become a nun... Whilst I didn't expect any better from him, I would have thought Heidi would have shown a little bit more class... before deciding to fornicate with the help."

Klum has now given a candid interview about her painful divorce by sitting down for an on-camera chat with Katie Couric, and the model-turned-reality TV host insists she was never unfaithful to her husband.

She tells Couric, "When we were together, I never looked at another man." Klum goes on to brush off about Seal's comments about her rumored romance, adding, "It was a unique choice of words... I'm used to it. Other people aren't." The interview, for Couric's new show Katie, is due to air on Wednesday.
